This license shows the "Any Ocean's" endorsement from having (finally) passed the celestial exam. (It took six hours to work up and complete the 20 problems on the exam).
It starts out with a star fix and tracks across the ocean to a port entrance crossing a time zone and correcting for set and drift, and obtaining a Longitude by running sun fix (One of the ones I believe I messed,
That was one that always gave me trouble)It requires making a 90% to pass, it took me 2 tries (and several thousand dollars in classes)to get it.
The 3000 tons was also added.
